My jeep has developed a whining/humming noise that only occurs during acceleration. The sound is vehicle speed dependent (the sound pitch gets higher) not engine speed dependent. On flat ground it isnt too bad unless I press the gas fairly hard but when at the top of a hill where the hill starts to level off, the vibration and sound is awful. Please help me locate the source and an idea of a repair cost.
Nope this sound only occurs while driving down the road. The sound becomes audible at 35-40+ mph but that could be because of the sound of the Flowmaster overpowing it at lower speeds : ). This sound only occurs while my foot is on the gas. I have checked the exhaust for anything rubbing or leaks and I found nothing. After three hours of driving above 55 mph this weekend Im preaty sure the sound and vibration is occurring somewhere in the front differential or front driveshaft or possibly transfer case or transmission. I can tell there is a little sound and vibration at the lower speeds but it's way to faint to locate below 35 mph. I do allot of driving above 55 mph in the summer as I go to Appomattox so this needs to be fixed before it drives me nuts!

I did look under it again and I found a slight problem with the driveshaft. I will try uploading some pictures.

WHAT SYSTEM DO YOU HAVE. TRANSFER CASE?
IF THIS IS PUSH BUTTON 4X4---IT MIGHT BE THAT SOMETHING DID NOT DISENGAGE. LIKE A FRONT HUB
THIS IS OFTEN OVERLOOKED

Nice jeep! Okay so I have checked the drive shafts for any play and I found none. I did get some pictures to show some possible causing things and I will put those on shortly. My system is a quadra trac two and it has a 247 J transfer case
